Specification of Letters Patent.

Patented July 8, 1913.

Application filed September 12, 1910. Serial No. 581,515.

To all whom it may concern Be it known that I, LINN Born BENTON, acitizen of the United States, residing at llaintield, in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Parallel Liners, of which the following is aspecification, reference being had to the accon'ipanying drawing,forming a part thereof.

This invention relates to instruments for cutting, drawing or n'iarkingparallel lines at various predetermined intervals apart. I ts mainobject is to facilitate performing such work with accuracy and generallyto improve the construction and operation of instruments of this class.

It consists in the construction, arrangement and combination of parts ashereinafter particularly described and pointed out in the claims.

.ln the accompanying drawing like characters designate the same parts inthe several figures.

Figure l is a plan view of a device embodying the invention; Fig. 2 is avertical cross section thereof on the line 2 2, Fig. 1; Fig. 3 a planview, similar to Fig. 1, showing the device without the cover plates,index or spacing wheel and operating lever; Fig. l: is an enlarged crosssection on the line et at, Fig. 1; Fig. 5 is a like section on the line5 5, Fig. 1; Fig. 6 is an enlarged detail view, partly in section, ofthe device for adjusting the liner laterally with relation to the workor pattern support and Fig. 7 is an enlarged sectional detail.

For the purpose of illustration a lining device specially designed foruse with engraving machines for cutting matrices for shaded letters orcharacters is herein shown and tlOSCl'lbOtl, but with little or nochange the device may be used :for other purposes within the principleand scope of the invention.

Referring to the drawing and more particularly to Figs. 1, 2 and $3, adesignates a horizontal pattern or work support, in the present case thebed of a matrix engraving machine on which the pattern to be traced isheld. it is provided on the rear side with ears or lugs 7) in which conepointed screws 0' are threaded in line with each other. A rod (2 isrotatably mounted at the ends on the points of these screws parallelwith the adjacent side and upper face of the bed a, and

on this red is mounted by means of lugs or cars c as indicated by dottedlines in Fig. 3, a plate or block f, which forms a support for thelining mechanism. The rod (Z passing through the ears or lugs c on theunderside of the plate or block f, also passes through a tubularadjusting screw which is threaded as shown in Fig. 6, in a lug or car71. on the under side of the plate or block f, and is provided with ahead i which has a swivel connection with a grooved collar y fastened onsaid rod (Z by a set screw 70.

A longitudinally channeled guide Z has a transverse plate or oll'set m,which is pivotally connected with the upper side of the plate or block fby a screw or pin n. The guide l, which is thus capable of angularadjustment on the plate or block f, is fastened in adjusted position bya screw 0 passing loosely through a hole in the plate or ol'lset m andprovided at its upper end with a clamping nut 71 and at its lower endwith a head working in an undercut curved groove in the plate or blockconcentric with the pivot screw or pin a.

A bar 7' preferably of square or rectangular form in cross ltjlllOll, istilted to slide in the channel of the guide Z and provided at or nearone end with a laterally projecting ruling arm 8, preferably at rightangles thereto, as shown.

In a recess formed in the upper part of the plate or offset m andintersecting at one side the channel in the guide Z, is rotatablymounted a drum If which is connected by belts u and '11 winding inopposite directions thereon with the bar 1' adjacent to its ends. Thebar r is formed on the side next to the drum t with a longitudinalgroove or channel to receive the belts u and c, which are stretched neartheir ends as shown in l igs. 1 and 7 over raised bearings on the bar tohold them out of contact with said bar and the opposing walls of theguide I between said bearings and the drum and thus prevent friction andwear. A single belt n, leads from the drum 6 toward the end of the bar'1', which is provided with the arm s, while two belts a, lead from saiddrum on opposite sides of the belt it toward the opposite end of saidbar, where they are adjustably fastened thereto by a sliding block infitted into a recess in the bar and tlu'eadml on an adjusting screw inarranged lengthwise of the bar, said block being formed with one of theraised bearings above mentioned. By means of this screw the head ofwhich is accessible through the adjacent end of the guide Z, the belts2) are stretched and kept taut so as to avoid any play or lost motionbetween the laterally movable ruling or guiding arm 3 and the rotarywinding drum 2?, which operates it and determines its position. i g

The rotation of the drum t, the circumference of which is somewhatgreater than the full traverse of the bar is limited to less than acomplete revolution, so that each of the three belts u and amakes but asingle wrap in winding thereon, and as they wind and unwind they arekept constantly in the same plane parallel with the guide Z, tangent tothe periphery of the drum and at right angles to its axis. This arrangement for. converting rotary into reciprocating or rectilinearmovement, avoids not only lost motion, but also any variation in therelative rate of speed of the drum and of the ruling arm, and it alsoavoids any strain which would cause excessive or unequal wear on themoving parts.

The channel in the guide Z in which the sliding bar 1" works, and therecess in the plate or offset m containing the drum t, are covered asshown in Figs. 1, 4t and 5, by removable plates y, 2 and 2. That part ofthe guide Z traversed by the endhof' the bar 1" to'which the arm 3 isattached by an offset shank 3, as shown in Figs. 3 and 5, is cut away onone side of the channel and the cap plate a is formed with a dependingflange 4 extending downwardly over that side of the channel and of thebar. The spindle 5 of the drum 2?, which is journaled in the plate orofiset m and the cap plate 2, is reduced and threaded at its upper end,on which are removably fitted interchangeable index or spacing wheels 6and a nut 7 for fastening said wheels thereon. Index or spacing wheels,having different numbers of notches in their peripheries for cutting,

drawing or marking lines different distances apart, are furnished witheach machine according to the nature and variety of the work to be donetherewith. To prevent these wheels from turning on the spindle of thewinding drum t, the shoulder or hub of the spindle'is provided as shownin Figs. 2 and 3, with a pin 8, which fits into a corresponding hole ineach of said wheels.

A lever 9 is pivoted or fulcrumed on the spindle 5 below the spacingwheel 6 and next to the cap plate 2 and is provided with a pivoted dog10 adapted when oscillated to engage with the notches in said wheel oneafter another, and to turn the wheel forward step by step predeterminedintervals corresponding with the distance between the notches and thethrow of the lever. The dog 10 is held in yielding engagement with thespacing wheel by a spring 11. To prevent overthrow of the spacing wheeland backward movement thereof with the Operating lever 9, a dog 12 ispivotally mounted on the cap plate 2 and is held by a spring 13 inyielding engage ment with said wheel. projection'l i which is adapted byengagement with the heel of the dog 12 to hold said dog in engagementwith a notch in the spacing wheel and prevent overthrow of said wheel asthe lever is brought to the limit of its advance movement. Thisprojection with the dog 12 serves as a stop to limit the advancemovement of the lever and of the spacing wheel. spring 15 connecting thelever9 with the plate 2, tends to turn said lever forward and hold theprojection 14 in engagement with the dog 12, as shown in Fig. 1. stop 16adjustably attached to the plate or offset m limits the backwardmovement of the lever 9 according to the spacing of the notches of theindex or spacing wheel 6. The dogs 10 and 12 are provided with pins orprojections 17 for throwing them by hand out of engagement with theindex or spacing wheel 6, in order to move the arm 8 back to its initialor starting position toward the plate or offset m.

The lateral movement of the guiding or ruling arm s is limited by stopscrews 18, threaded in the end plates 19 of the guide Z in position toengage with the ends of the sliding bar r. i

The device when used in connection with a matrix engraving machine isadjusted and operates as follows: A raised pattern defining the outlineof the shaded character or design to be cut in the matrix is fastened inplace on the bed a, the liner being turned up on the hinge rod cl toreadily admit of this, The liner is then turned down into place with theguide Z and arm 8 in a plane parallel with the pattern and shiftedlater-, ally lengthwise of the rod (Z into approximately the properposition relative'to the pattern by loosening the set screw and slidingthe instrument with the adjusting screw 9 on said rod, the guide Z andarm .9 having been turned on the pivot screw or pin 7t and locked by thethumb nut 29 in the desired angular position on the supporting plate orblock f, for cutting or tracing lines at the desired angle or in thedesired direction across the face of the matrix or design. The set screwis being tightened to lock the collar on the rod (Z, the liner isadjusted laterally to exact position by turning the adjusting screw g.

The liner being provided with an index or spacing wheel 6 having therequired number of notches to produce the desired spacing of the linesto-be cut orv traced and the arin 8 being set with the parts in posi-The lever 9 has a isq.

tion as shown in Fig. 1, to make the first cut or line, the tracing toolor follower of the engraving machine is moved along and in constantcontact with the front edge of said arm from one side of the pattern tothe other, its movement being limited by the raised shoulders or ribs ofthe pattern defining the outline of the character or design. Thismovement of the tracing tool or follower causes a corresponding movementof the cutting tool of the engraving machine across the face of thematrix in which the grooves for shaded lines are to be cut. The lever 9is then drawn by the operator back against the stop 16 which has beenadjusted to correspond with the spacing of the notches in the wheel 6.During thls operatlon the wheel 6 is held in place by the dog 12 whilethe dog 10 is carried back into engagement with the next notch. Thelever being released by the operator, is thrown forward by the spring 15turning the spacing wheel 6 an interval exactly corresponding with thedistance between adjacent notches in its periphery, and the arm 8 ismoved laterally a corresponding distance forward or away from the plateor ofi'set m by the belts o winding on the drum t. The tracing tool orfollower is then moved back along the working edge of the arm 8 betweenthe outline defining shoulders or ribs of the pattern, causing thecutting tool to make another groove in the matrix parallel with thefirst. These operations are repeated until the work is completed.

For cutting the shaded face of a matrix of a smaller size than anotherwith a given pattern, the same pattern being employed for cuttingvarious sizes, an index or spacing wheel 6 having fewer notches, spacedfarther apart, is used, while for cutting the shaded face of a matrix ordesign of larger size than another with the same pattern, an index orspacing wheel having a greater number of notches closer together, isused.

The device may be used for cutting, drawing or tracing with any kind ofinstrument, parallel, vertical, horizontal or oblique, continuous,broken, straight, curved or zigzag lines, directly or indirectly, onpaper or other material placed on the bed a or other suitable support.

Various changes in the details of construction and arrangement of partsof the device may be made to adapt it to the various uses and kinds ofwork to which it is applicable, without departure from the principle andscope of the invention.
